1. Bacterial and fungal growth in soil: The effect of temperature and substrate addition
Abstract : Bacteria and fungi are the main agents in decomposition of soil organic matter. Their activity is determined by the availability and quality of substrate, especially its content of carbon, but also nitrogen and phosphorus. Other environmental factors, which affect the activity of the microbial community in soil, are temperature, moisture and pH. READ MORE

2. On the Ecology of Saprotrophic Fungi and Bacteria in Soil: Biotic and Abiotic Control of Growth Rates
Abstract : Two groups of organisms dominate the decomposition in soil: fungi and bacteria. One of the most important parameters to optimise for any organism is its growth, and thus a direct way to study the effect of environmental factors on fungi and bacteria in soil is to measure their growth rate.

3. Soil microbial responses to mild winters and seasonal change
Abstract : The aim with this thesis work was to study microorganisms response to milder winters, different seasons, and altered temperature. Winter warming treatments were established in a semi-natural temperate grassland, simulating mild winters for two years. READ MORE

4. Effects of temperature and terrestrial carbon on fish growth and pelagic food web efficiency
Abstract : Both temperature and terrestrial dissolved organic carbon (TDOC) have strong impacts on aquatic food web dynamics and production. Temperature affects vital rates of all organisms and terrestrial carbon has been shown to alter the dynamics of phytoplankton and bacterial production and affect the trophic structure of planktonic food webs.

5. Effects of Vibrio cholerae protease and pigment production on environmental survival and host interaction
Abstract : Only two out of more than 200 V. cholerae serogroups, classified on the basis of LPS structure, are associated with epidemic or pandemic cholera. These toxigenic serogroups carry phage-derived pathogenicity islands coding for the main virulence factors for establishment of cholera disease – cholera toxin (CTX) and toxin-coregulated pilus (TCP).
